I ordered a bowl of soup around 4:30 pm on a Friday. The soup was good and I ate quickly in about 15 minutes because I had a 5 pm meeting to catch. I put my bowl away and sat back down to wait for my laptop to shut down. Immediately, a waiter set a sign on my table saying that tables are for eating customers only and, something to the effect of, it's time to politely leave. I could see no one waiting for a table and nor anyone in line to order food. I had been inside for less than 20 minutes total....The soup was good and ambience was nice, but this experience really rubbed me the wrong way. Also no wifi so....I'll find a different cafe next time!
