You know, I've never been to Slow's!
LOL. You're going to be rolling in Mexican food. If you do come to Detroit, try Armando's in Southwest Detroit. The neighborhood its in is really fun and there are big park across the street where people take their kids. Armando's has some really GOOD food...but if you want to try different things, there are also older women who sell their dishes, you just have to get lucky enough to see one.
Theres another Mexican Restaurant that I just cannot remember the name of...it is also a great place, all I know is that there is a Bakery across the street from it that is pretty popular.
