My wife and I went to 5 Rabanitos tonight and tried several of the dishes. I really wanted to like the restaurant, but I'm afraid that there were many more misses than hits, so we won't be returning. It's too bad, as we're both getting more into the Pilsen neighborhood and it would have been good to add this place to the options.
There's a nice vibe to the restaurant. It's simple and colorful, with a partially open kitchen. The server was really friendly and helpful.
But now on to the food, where it went downhill. We started with the guacamole with the tomatillo salsa and 3-chili salsa (no photo). The salsas were both excellent. The tomatillo salsa was smoky, with a little bite on the end. The 3-chili salsa had a nice freshness to it. The guacamole was good, but nothing special.
Sopes - Pibil, Carnitas, Beef Barbacoa (left to right)
I liked the Pibil and Barbacoa sopes. The Pibil had a good spicy bite to it, and I liked the pickled onions. The Barbacoa was flavorful, with the radishes providing some crispness. The Carnitas were a flop, with the pork being bland and almost tasteless.
Tamals - Golden Carnitas Tamal, Tamal Vegetariano

Both of the tamals were a flop. I will admit that I'm not a mole fan, so I tend to not comment on them (although will in a moment). My wife does like moles, but she didn't like either of these. As you can see, both of the tamals were literally swimming in mole, so there was plenty for us both to try.
The Carnitas Tamal suffered the same blandness that the Carnitas Sope suffered. There was a decent amount of filling, albeit flavorless. The tamal itself was constructed and cooked nicely. The mole was sweet and tasted somewhat milk-chocolatey.
The Tamal Vegetariano was also pretty bland, as was the mole it was swimming in. I think there was a decent amount of filling but it was hard to tell under all the stuff that had been ladled on top of it.
Cuban Sandwich
The Cuban was well constructed, but again bland and tasteless. When ordering, my wife asked if there was a pickle on the sandwich as the menu didn't note it and it's a staple on any sandwich wanting to call itself a Cuban. The waitress said there was, but she must have misunderstood the question, because there was no pickle. The menu states that there is supposed to be a "spicy chipotle cream" on the sandwich, but if there was it didn't lend any flavor. We did take half of this home so we could add a pickle and some mustard to try to wake it up.
Perhaps the dishes would have been better if Chef Sotelo had been in the kitchen. However, he spent the time we were there sitting at a table talking with a couple of guys who were working their way through a 12-pack of Corona bottles that was sitting on their table. When we didn't want to take the tamals home, the waitress asked if we didn't like them, to which we were honest and said no. She took them over to the chef and had a conversation, then came back and said they would be taken off of the bill. That's nice but we told her we expected to pay for them because we ordered them. In the end, she insisted.
Lastly, I think it would be good to ditch the radishes on every dish. I get it that it ties to the name of the restaurant, but it does come off as a bit odd with them on everything.
So if you go, stay away from the Carnitas dishes, and order more of the salsas to add to your dishes to give them some added flavor.
