Just been trawling through the same situation. Some damn depressing ones out there. I checked out Mayfield (great garden but a bit poky inside), Sinclair and Hyde n Seek Templeton (trying hard but no outside space). Settled on the Bridge End one in Gorbals - it was the only one I saw that had loads of colour and space. Dropped in 3 times uninvited and it had a really happy vibe on every visit. Don't know if this helps?
Heard good things about Poppins and Nithsdale, by the way.
