All the above are Italian BTW.
If you fancy traditional English grub, try Sams Chop House (opposite the Royal Exchange Theatre, just off Cross street), or if you fancy pushing the boat out and don't mind a bit of a walk or a short taxi ride, can heartily recommend The Angel.
About a mile away from your hotel, but spectacular food. Bit of a scruffy industrial area,just outside the city centre, but one of the nicest restaurants I've ever been to.
Can't forget the Market Restaurant in the Northern Quarter, which was the first really, really nice European style restaurant in Manchester and has been going for yonks. The Northern Quarter Bar & Grill next door is also very good.
Haven't had anything to eat yet, can you tell?
