Italian food I dunno much but for that budget, I suggest The Imperial Herbal Restaurant, 3rd floor metropole Hotel, 41 Seah Street. For reservation call +6563370491 or +6563315112.
Dunno if the number are still valid as I had not been there for a long time liao. If you have flu, try their herbal tea. I mug sure cure one. Got Tiger that thing too if you want.
