I know of a few good happy hour deals but need more.
E.g., Fox & Hound have $2 pints on Tuesdays but I could not stand the noise when I went there a few weeks ago and had to leave right away.
I once went to JJ Bitting and liked it but it is a bit out of the way and food choice is limited for veg. Pizza was not that good.
The Brownstone in Metuchen was not worth the trip.
Romano's have a happy and reverse happy hour staring at 9:30pm.
Wish I know of more places.
