I've seen that place but not gone in. Surprised you didn't rate Hubbox. I love it there.
That reminds me, there's a good self service all day,all you can eat breakfast place called Brody's. It's not the cheapest but boy can you load up on a fry up/pancakes/etc.
Brodys is excellent, I think part of Hubbox problem for me was it was so cramped and packed and I had very poor service, 75% of the food is pretty good but for burgers Urban Burger beats it for me.
Urban Burger is about 50 yards down the same road as Brodys which is right opposite the museum, which if you like museums is a very good one, being under 30 miles from me I visit it once a year probably, I eat out in Exeter probably 8 times a year, I like the city but its not so much of a "young" city but that does seem to be changing but at my age I avoid any student oriented pubs now.
