I personally love Bella Nails, but there are loads of options in Ballard. Didn't love Hoa. LT is also great (just a further walk for me!).
Anyway as for the new one - I haven't had flyers pushed at me, but I have noticed they are never busy (not like LT or Bella). Never a good sign, especially since they're offering discounts right now. I feel like the name starts with an R.. like RB nails or something like that..
