Californos (4124 Pennsylvania, 816-531-7878) is nestled just south of Westport Road amid shops, restaurants and other bars. The warm and inviting place is well-known for its self-declared "restaurant redefined" status, and it even serves as a wedding-reception venue. The wood-and-brass bar is just a few steps from the front door, and the liquor assortment is vast, with a cocktail menu and a wine list that change with the seasons. Most nights of the week, Californos hosts live music: live reggae on Fridays, the occasional jam band on Saturdays and house music on Sundays (Sunday Solace with DJs Trevor Shaw and Sasha Tru). There's usually an open-mic night on Mondays, except for every third week, when the Opera Dinner takes over. And on Wednesdays and Thursdays, singer-songwriters typically perform. Californos is slightly upscale but not intimidatingly so. Happy hour goes from 3 to 6 p.m. Monday through Friday, and features $2 off appetizers, wines by the glass, and Boulevard Wheat and Pale Ale pints.
