This month let's check out House Bar! I've never been but I've heard great things: friendly, cheap, unique... Part of its schtick is that it's really small, but apparently they have a patio, so if it's nice out, that could make for a really pleasant spring evening -- though the inside sounds cool too!
The bar is cash only, but has an ATM.
Also, please remember that we're collecting member dues of $10 per year to keep the group going (the site costs $19/month). You can pay easily online from the left sidebar, or pay cash at a Meetup. Thanks for helping!
