I had Sunday lunch in the Antiquary on St Stephens Street a few weeks back.
Had steak pie and chips and enjoyed it a lot. Home made which is a feat in itself for a lot of pubs, tender meat, rich gravy and crispy chips. Nothing fancy but reasonable and decent.
Also ate in The Bon Vivant on Thistle Street back in early June. Wine list was great if a little pricey. Tried a few things on the menu as it's 'tapas' style. Again enjoyable whilst not being overly exciting. The dressed crab was the highlight, pork belly was nice whilst the duck was chewy, overdone and disappointing.
