I work nearby and would say the crowd there is VERY local. Shops there are even more dull than those at Tampines. The same goes for restaurants & cafes. Unless your target customers are those aunties/uncles, I don't think you'd get much of attention.
Oh I wish there were nice lunch places at Eastpoint though, like O'Briens, Cedel, the Soup Shop, etc. Sigh. Perhaps you could help??
Good luck.
