I walked across the river to Bob Chinn's Chicago branch today at lunchtime. My husband and I were there when it was open just a few days, and weren't impressed, but realized that it was unfair to judge them so soon after opening.
I had a cup of their gumbo, and it was pretty good - not with the level of spice I would give it if I was making it at home, but way better than Heaven on 7's gloppy stuff (which I like anyway, incidentally). It was made with crab, fish and sausage, and was chock full of okra. I could taste the file gumbo.
I then ordered their tempura fried shrimp, for $9.95, and got a huge plateer of crispy shrimp and fries - 15 good-sized shrimp - way too much to finish (especially after last night's Fogo blow-out). The batter was incredibly crisp, and stayed that way throughout the meal. They didn't serve it with a tempura dipping sauce, but then it really wasn't a tempura batter after all - I'm not a batter expert, but I know that a tempura batter is just flour and water, and turns out very light. This batter was more "American," and though not overly thick, was heavier than the Japanese variety. But I'm not complaining. It was a good meal and a good value.
