Bills has lots of different spaces - veranda, al fresco courtyard, dining room and public/front bar.
It offers good quality, honest food of generous proportions. If you're not a big eater, either share a main meal or order a half serve for a small surcharge (half menu price plus $2).
During busy periods (long weekends and school holidays), be prepared to wait up to 45mins for your meal. Or order well before 6pm. Definitely book a table.
