Congee Village has been recommended a couple of times here in the past couple of weeks to people (including me) looking for a place to go with a group of friends.
I went last night, and just wanted to add a couple of notes...
We originally wanted a private room for dinner and karaoke. There were 8 of us, and a 12 person room would have cost us a minimum of $400. It would have cost each person over $30 each, which isn't terrible, but the main dishes are mostly under $10, and appetizers under $5. With beer being $3, we all would have ended up having to drink A LOT to meet our quota.
We got there early, and they wouldnt seat us till the whole party was there (I know this is common, but I HATE this policy). We parked ourselves at the bar and chatted with the friendly bartender in a bowtie, and watched him make exotic drinks (the small bar is well stocked with everything from fresh lychees and watermelon, to tapioca balls).
We got a regular table, each ordered a main course, a bunch of appetizers for the table, and a couple of beers each. We split the bill evenly, and it cost us about $17 each.
We had a blast trying everything from turtle soup amd frog porridge, to sesame chicken and mixed vegetables for the more picky eaters.
The service was slow, and they brought things out one dish at a time, so some people sat waiting for their food long after other plates had been cleared. This was probably to make it more family style, but, for example, the vegetarian of the group was left watching everyone else eat for a while before any meatless dishes were brought out.
It was fairly loud and crowded in the place, but we were able to all hold conversation without a problem.
I would definetely keep this in mind for those people asking for a fun, inexpensive place for a group birthday or celebration.
