Hi all, I am in NYC and was wondering if I can get some recommendations for LN2 system installer? I don't need a super sophisticated system but was thinking about those typical setting where you have a large dewar tank and it's dispensed through a pipe. Do any of you have a similar system set up? If so, how much did it cost? I am trying to incorporate in in my kitchen but was afraid of using portable dewars. Thank you in advance for your ideas!
