Don's Pie Club at China Square Central is nice and comfy with
sofa seat available.
Canelle Patisserie & Cafe by Les Amis at the Singapore
Repertory Theatre Bldg near UE Square also has very nice ambience
and fabulous fabulous pastries. Only I'm not sure if reservation of
seats is allowed.
Cafe Domus & Wine Bar at owen Road is also open for poetry
reading activities, tho I have to admit the price for drinks and
snacks is abit on the higher than average rate. It has an open
rooftop gazebo thing which is very private. Nice ambience at
nite.
