The Ben And Jerry's at Raffles city is pretty much a open concept. There aren't many seats and the tables are small. So it's not recommended that you go there in groups. If you do, perhaps you would have got to sit at seperate tables.
It's fine if you just sit there for a while to finish your ice-cream. I personally don't like it there as it is rather noisy cos it's open.
However, their ice-cream is as usual, up to standard.
My favourite would be their mango sorbet. You've got to try that man. It's the nicest.
