I am new to the sushi world and I am in search of great places in or around a couple of areas. I love Sushi Hana (the David Roll and Crunchy Salmon are my faves) but I live in Mt. Washington and it can take me 30 minutes to get there if the traffic is bad. Also, I travel for work every week and return to Penn station (Charles St.) on Thursday evenings, often craving sushi. So my question to you is this: where can I get decent sushi in or around Mt. Washington and/or Penn Station?
