Thirty to one hundred guests is the awkward middle size of Bangkok party planning. Too many for a long restaurant table, not enough to justify a hotel ballroom, and exactly the size where “we will figure it out on the night” stops working. If your birthday, farewell, reunion or company party falls in that range and you want it in the Ekkamai and Sukhumvit corridor, this guide covers the real options and the questions that separate them.
Why the 30 to 100 guest range is tricky
Most bars and restaurants are built around walk-in tables of two to eight. Groups of thirty are handled with a reserved zone and a minimum spend, which works until a stranger wanders through your birthday toast. At the other end, event spaces built for 300 feel empty and price like conferences. The venues worth finding are the ones sized so your group can take the entire place.
What “private” actually means
- Full venue buyout: the doors are yours. Your guest list, your timing, your atmosphere. This is the version most people picture when they say private party.
- Private room: a genuinely separate space inside a bigger venue. Great for 10 to 20, but the bar and the energy stay shared.
- Reserved section: a roped-off corner of a public floor. Cheapest, and the least private of the three, whatever the listing says.
Three questions expose which one a venue is really offering: Is anyone else in the building during our event? Do we control the timing and the format? And is there a minimum spend on top of the hire fee, or one transparent price?
The Ekkamai and Sukhumvit corridor
The stretch from Asok through Thonglor to Ekkamai is the easiest part of Bangkok to gather people: one BTS line, endless taxis, and most of the city’s nightlife within a short hop. Rooftop bars here do reserved zones with views and minimum spends. Japanese restaurants and izakayas hide excellent private rooms in the 10 to 20 range. Club floors privatize for bigger budgets, mostly late-night. Activity venues, from karaoke to gaming lounges, are where full buyouts for mid-size groups actually exist, because the whole venue is already built around groups playing together.

The full takeover option at Bamboo
Bamboo Gaming Center and Bar, on Soi Ekkamai 22, hands over the entire venue for private parties of 25 to 110 guests. That means a console lounge seating up to 40 at a time across more than 15 PS5 stations, three racing simulators for time-trial bragging rights, a private gaming room for up to 10 people with 3 PS5 consoles, 2 Nintendo Switch consoles and 3 screens that becomes the VIP corner, and a full bar running for your guests only. Outside food delivery and cakes are welcome, drink packages are available on request, and there is free parking under the building, with BTS Ekkamai a short taxi or motorbike hop away.
It works as the whole evening or as chapter one: doors from 14:00 and last call at 02:00 leave room for both. Planning a birthday specifically? Our birthday venue page covers those formats, and bachelorette groups have their own playbook.

Planning pointers for a mid-size party
- Count RSVPs pessimistically: Bangkok attendance runs about 20 percent below the group chat enthusiasm.
- Book weekend dates two months out; venues that do real buyouts hold limited slots.
- Decide the food plan early: in-house, delivery, or a cake plus bar snacks.
- Send one logistics line with the invite: nearest BTS, taxi drop point, parking.
- Confirm what locks the date. At Bamboo it is a 50 percent deposit, with the balance settled on the day.
Frequently asked questions
Where can 30 to 100 people hold a private party in Ekkamai?
Look for venues that offer genuine exclusive hire rather than a roped-off section. Bamboo Gaming Center, near BTS Ekkamai, runs full private takeovers for 25 to 110 guests: the entire venue, the bar and all the gaming equipment reserved for your group only.
Can we bring our own cake or catering to a private party?
Policies differ by venue, so always confirm before booking. At Bamboo, outside food delivery and celebration cakes are welcome, the bar handles the drinks, and event drink packages are available on request.
Is private venue hire expensive for a group?
Usually less than people expect once you split it per person. Bamboo prices venue hire per guest, the rate slides down as the group grows, and it covers the space, the equipment and the staff in one number. Current rates for selected group packages are listed openly on the events page. Other group sizes receive a tailored quote.
How late can a private party run in Ekkamai?
Bamboo is open from 14:00 to 02:00 every day, so an evening party can run well past midnight without a venue change.
