Enjoy your stay at the Lancaster Arts Hotel, it's great.
Some restaurants not listed that are great too:
Molly's Pub - East Chestnut
Belvedere- North Queen
Effie Ophelpia - Prince
Annie Bailey's Pub & Restaurant - W King - Pub brought over from Ireland
Great Sushi just south of Lancaster city at Wasabi in Willow Street, Kendig Square shopping plaza, it's an odd place to find the best Sushi in Lanc. County!
Have a great time in Lancaster!
The Lancaster Arts Hotel has a stellar restaurant on site. Unique and innovative cuisine. To the right of the hotel is a repurposed factory building that has some shops and restaurants. I have heard good things about "Fenz" and that their wine list is good, but I haven't been there myself. Also with in walking distance is The brickyard. This would be good for lunch. They have a good beer list and serve solid pub food. If the weather is OK, I would recomend a walk to Central market for breakfast and shopping/strolling. Have a great time!!
