#4 - Taishoken - Classic tsukemen. I was actually expecting a more flavourful broth and was pretty underwhelmed by the quality. Pork slices and ramen egg were great. 
#3 - Hinodeya - I'm a sucker for dashi broth. Their portions are very generous which always wins extra points in my book. Pork is actually thicker which I actually prefer. Menma and ramen egg were on point. My go-to ramen spot in SF that doesn't completely destroy your wallet.
