Ok, there was lots of anticipation on this one, and I live relatively close, so I went to check it out tonight on their first night.
Only had the chicago deep dish pizza. Well, it is nowhere near little star or zachary's. It is more expensive than little star (by a couple bucks for a pizza for two) and it is not as good for the crust (LS is richer and has a better texture), for the sauce (LS has a chunkier sauce with more personality) and for the toppings (too much cheese, I am sure it will be hard to digest).
Anyhow, the space is nice (a bit bare for now; luckily the flat screen tvs were off), the service is focused (I found service a bit spaced out at LS) and the pizza is nonetheless decent. It is better than 90% of the deep dish pizza in the city. It's just not as good as LS.
