I'm not sure if it was the time (after midnight) or the size of our group (6), but they have an odd policy of no more than 3 separate checks at a table. However, they're open 24 hours, which is very convenient.
We were all talking amongst ourselves, so I kinda lost track of time, but service didn't seem exceptionally speedy. My water wasn't refilled promptly, and I think they only had one server on duty. The food was fantastic, though. My chicken soup was very chunky & delicious, and my tater tots were crisp & tasty.
