I actually quite like LunaBar Coffee in Penang for its ambiance. Outlook is certainly very green as it is filled with plants. It is hard for you miss it as the most unique one. One of a cafe in Penang that you can plan to visit.
Nicely decorated with taste of art and scandinavian style. Most of the souvenir place on table are able to purchase.
Outdoor seating area with the nature. 
Love the vibe of indoor seating area, as it certainly do feels like a cafe in Taiwan.
I find coffee here are okay only, as there are better one out there but certainly in for their ambiance.
It is a nice cafe to chill with is environment. Seems that alot studens are here parking themselves to work. So be prepare to get a spot from them.
