if you are meat eaters I recommend Peter James butcher at Crofton Park, also there is a little co-op and a Budgens there. I usually go to Sainsburys at New Cross Gate on the way home to HOP - it is quite large and has a meat and fish counter. Lewisham market on Saturday is great for fruit and veg, and there's an excellent Italian deli there near Santander. There is also a food market in the car park at Lewisham College Saturdays 1000-1400. If you are after a gym the one at St Dunstan's school is reasonably priced although only open out of school hours.
