Check out the new Frisco Grille if you're in Columbia. Their website isn't up to date yet - they just relocated and reopened a week or so ago.
I hear they now have 29 taps of micros and an expanded menu. They'll be brewing their own beer soon.
New location is on Dobbin Rd near intersection of McGraw - hopefully they update the website shortly.
Frisco Grille and Cantina
If you're in Baltimore, Max's can't be beat for selection - over 100 taps, over 300 bottles.
If you want sports and English ales, head to Pratt Street Ale House across from the convention center.
If you're looking for a smaller, cozy environment with friendly bar staff and descent food - check out Muggsy's Mug House on Light St in Federal Hill. For those of you old-timers, it's where Sean Bolan's used to be.
A dozen micros on tap
