Mid-Summer Lounge is one of those places you really want to like. Most of the places that serve Chinese food in Champaign are not really authentic, so my expectations have been tempered.
I'll start with the good:
The food is here is great - I got the Beef and Onion dumplings and they tasted great (a plate of dumplings is $9.81 with tax). I would recommend dipping dumplings in the Chili sauce and eating them. The interiors are pretty cool and honestly much better than most other stores in Campustown.
The bad:
The service here needs serious work. It seems like most of the staff cannot speak English, and to order, I had to enlist the help of customers who could speak Chinese. There is "menu" on the wall made out of wooden placards, but everything is written with Chinese characters. There is no English menu. I get wanting to stick to your "theme" of not having English on the walls but what really makes it worse is that your staff cannot help customers order either (because they don't speak English).
It will take a while for your food to be made because it is prepared fresh. It took almost 30 minutes to get my order. Since I was warned beforehand about how long it would take, I agreed to wait. But service here is really slow and you'll need a Chinese friend (or at least know how to say what you ordered in Chinese) when one of the staff comes out and calls out the dish you ordered.
It's a cool place and the food tastes great but I don't think I'll go back until the service is better.
