I've got that app, meh...also taphunter and FindMyTap. None of them are really "good", spotty info and hard for you to provide input/update as a drinker. And NONE of them is worth a crap at finding real cask ale.

I walked all over DTW recently looking for beers, hit probably 7 places. I hate to say it, but I think the Buffalo WildWings place was actually the best beer selection. I have been to Jacoby's three times, I give it a thumbs down. Bottles only, not the german-beer-drinking crowd I was looking for.

And if anyone gets told to go to GreekTown for BBQ at "Red Smoke"-- PASS, that place is probably the 2nd worst BBQ ever eaten, behind only when Uncle Bob's pigsty caught fire and he didn't want to waste...
