Restaurants
Turmbrauhaus
Neumarkt 2, (http://www.turmbrauhaus.de). open every day from 10am. the mixture of a traditional wooden interior with copper brewing vessels and home brewed beer make this a great place to sit down, relax and enjoy an evening. the food served here comes from saxony/bavaria, is very good and also reasonably priced. get there relatively early if you want to be able to pick your table. a night club can also be found in the basement.
There are several good, reasonably priced restaurants dotted around the main square in front of the town hall. Several have tables and chairs extending out into the square, something worth doing if the weather good.
snacks
Again situated around the main square, bakeries/butchers can be found. If the market is on, there are also several Imbiss stalls selling freshly cooked sausages and other snacks.
