Even when the sun is beating down outside, Hammerstone’s (2028 South Ninth Street, 314-773-5565) maintains its darkened bar cool. That’s thanks to the shades on the windows, sure, but it’s also a testament to the Soulard watering hole’s relaxed atmosphere and blues-bar vibe. Hammerstone’s is the perfect place to put back a few cold ones and hide from the world, but with its friendly bartenders and amiable clientele, it’s a great place to strike up a conversation with a stranger as well. And with a sizable patio just out back, you can brighten your drinking experience with a little sunshine too, if that’s your thing. Hammerstone’s is open Monday through Friday from 6 a.m. to 1:30 a.m., Saturday from 8 a.m. to 1:30 a.m. and Sunday from 9 a.m. to midnight.
