Hukdizzle, don't believe the bull**** about Detroit. it's the most misunderstood city in the world. If you want to check out an awesome microbrew you need to go to Motor City Brewing Works: Home Motor City Brewing Works, Ph. (313) 832-2700
It might be a bit too far to walk from your hotel but it is a $5 cab ride up woodward (make sure you tell the cabbie to go on the meter or he will definitely screw you because it's a short trip). If you want a good beer selection downtown, Foran's on Woodward is an excellent choice. Atwater Block brewery is a bit further up the river on Jefferson if you want to try another microbrew, but I think Motor City is better. If you want a place you can walk to from your hotel, Detroit Beer Company on Broadway is ok.
So, I live in Detroit, near Motor City Brewing, and have lived here for several years. It is a great city with tons of amazing people and excellent bars, restaurants, venues, etc. The problem is there is a lot of crap as well, and most of the tourists get steered towards the ****ty places because they are easier to find. Downtown is not any more dangerous than other big cities, and just like those big cities you need to use more common sense. Be open minded and try to look at Detroit from many different angles. People who focus on a few blighted spots here and there miss what an amazingly interesting place this is.
