This is a reasonable size Costa. It has a few nice square tables, and one large table which are reasonably comfortable. The round tables at the back with the long sofa aren't a good idea because the table is then too high and it's an awkward angle to type. The food and drink are nothing special - it's just a Costa after all. Wifi worked great for my entire stay of about 4 hours. But there is a big issue that makes me not recommend here - it's freezing inside! The AC was cranked up and there was a cold breeze everywhere I sat. When I walked in I thought this was nice, but it wasn't long before I was uncomfortably cold.
