Number Thirty Eight is an RiNo staple that does the indoor-outdoor thing right. The sprawling patio, food trucks, and rotating lineup of live music and DJ sets make it the kind of place you show up to for one drink and stay for four hours. The vibe is casual but alive - think converted warehouse energy with a crowd that mixes craft beer enthusiasts, concert-goers, and neighborhood regulars. It punches above its weight for a bar, hosting everything from local bands to bigger touring acts. If you love discovering new music in a setting that feels more backyard party than formal venue, this is your place. Best on a warm Friday when the whole thing opens up and the city remembers why Denver summers are special.
