I used to go to cakeshop a lot, but after the staff treated my friends and me badly, I can't support a venue that doesn't make loyal customers feel welcome. It used to seem like a cozy place to hang out on the Lower East Side, but it's hard to enjoy a quiet read or cup of coffee at a place where you're not treated nicely.
One staffer behind the counter lied to me about the price of a cake slice so that, as she told me, she would definitely have tip money, and then told me never to come back to cakeshop when i-- of course-- didn't leave a tip. My friend was actually beaten up by one of their weekend bouncers, ruining the performing band's night because he's their friend, too. That incident pretty much sealed the deal with what I think of cakeshop.
It's too bad, because it's almost like a DIY venue in manhattan, but if you're gonna go for that vibe, go to Pianos next door and skip the cake.
Pros: homey decor
Cons: rude staff
