Song Be describes itself (if Google translate can be trusted) as having a rustic old Asian furniture and with the warmth of wood and cloth. This is certainly true the interior has a strong Vietnamese theme as does the menu but along with some Thai dishes and, of course Japanese food.
The first time I went I was feeling a bit adventurous and tried something new; their Zenzai. I didn't like it but it's good to try something new every now and then. Song Be is tucked away but I located right next to the tracks of the JR Kamakura station. It's usually pretty quiet in the day and is a great place to relax and get a few letters written. I suspect it's probably busier during the evening.
There are selection of books, toy and knick knacks as well as local postcard, jewellery and other handmade wares available. There is lots information on local events and stores with lots of cute business cards and flyers as you enter I always take a few for my TN or my letters. Song Be is one my fav places whatever the weather to hang out in that isn't too far from home.
