I cannot stress this enough: Steamers gave me the best espresso I've ever had, hands down. I work at a coffee shop in Riverside, and I take some amount of pride in our espresso and our methods of extraction, but never have I tasted such wonderful, smooth, thick espresso as Steamers.
Coffee aside, Steamers is a good place to relax and to have a sandwich (the roast beef is good; the au jus sauce is average). The only thing that's ever disappointed me there is the occasional flaky service, and the awful bagel I had one morning (whipped cream cheese, piled on for days, and way overpriced). Go watch some relaxing jazz in the evening time. Visit or call them for their ambitious schedule of events.
