Done it umpteen times at Tannadice and never had a bad day. Someone i know hires a box above the tunnel so did that a few times as well and preferred that tbh. Smart casual rather than suit, tie etc and although not a 3 course meal, it was a hot buffet plus a free bar the whole time we were there. Also did Dens once for a workmates 60th and thought that was better than ours. The servers were never away from our tables and brought fresh drinks as soon as we got halfway through our current ones
