I’ve lived on the Progress Estate (on the side nearer Westmount Road) for about two years - I have to say some of the reviews of poor old Eltham on here are very harsh, although I appreciate I live in one of the nicer bits! We moved here from zone 2 in order to be able to afford a house with a garden.
The Progress Estate itself is lovely, and feels very safe - as do all the Glen- roads around Eltham Park and Westmount Road. The demographics are changing as lots of recent probate sales on the estate tend to go to young professional couples priced out of naicer bits of London (often commuting to Canary Wharf, the City or Westminster). There are several nice cafes and pubs - restaurants remain far patchier, although as someone mentioned there’s a new Italian restaurant opening up and you can always get a fish supper from Hooked on Westmount Road... For brunch, there’s Westmount Cafe and Chez Maitre, as well as Bob’s Your Uncle on the high st by Sainsbury's. For lunch, Eltham GPO does good small plates (as does the SkyBar actually) and the Rusty Bucket does toasties on a Sunday. Tudor Barn on Well Hall Road does decent pub grub, and has a nice outdoor seating area in the summer.
The High Street is functional enough, although there’s an ominous trend of shops being replaced by gyms. There’s a cinema and also the Bob Hope Community Theatre. The Rusty Bucket - an excellent pub btw - puts on various events, like beer tasting. The parks are great compared to zone 2, and there’s some walks around Eltham Palace which feel like you’re in the countryside but with an unexpected great view of the skyline.
Negatives - the new SE timetable is nonsense, and the buses to Woolwich could be more frequent. Other parts of Eltham are definitely more unreconstructed. Also, there’s several huge roads.
