i went there, in November i think. Its no Kew Gardens but its a fair effort i guess. Quite immature still so would be interesting what its like in a year or two as stuff seems closely planted. Found some labelling was swopped around too so then couldn't be sure that the plant i was looking at was the one the label showed, not sure how much attention is paid by the 'top guy'. There is a small playground there, with a splash pool and a big taverna. It costs to get in (can't remember how much) as well but if you eat you get that entry discounted. The veggies in the 'traditional' museum were non-existant or looking very sorry for themselves, but was November which technically is winter right ?
Despite all that, will go again in 2010 !
