Restaurant Review

I went out to dinner last night with my husband, brother-in-law, and sister-in-law. We tried to get into River North's Frontera Grill/Topolobampo (which the Obama's love) but were told there was a 2 hour wait. (6pm on a Thursday night) We ended up eating at Mambo Grill on Clark, which was unexpectedly good. (I had never heard of this restaurant) The food was outstanding (I had BBQ citrus salmon topped with a fruit and vegetable salsa) ... but the service was very slow. This area of River North has a ton of restaurants that are off the beaten path of Michigan Ave. The other 2 restaurants I want to try in this area include Rockit Bar and Grill and Hub 51.
