It was not really one sandwich, they were two. And it was not just any "vis", it was smoked eel. And then there were charming Rob, and delicious breads to choose from. And even if eel is not as abundant in the sea as it used to be, it WAS in my eel sandwiches for only €4.50 each! You can try to improve on your sandwiches with pickles, onion, maio and what-have-you, my husband always does that, but I'm faithful to my motto "Why spoil a good thing?" Smoked eel needs no improvement, any other flavor will take away from the smoked taste of eel.
Rob closes shop at 4PM, so if you want your sandwiches for an early evening snack or even dinner, ask Rob for "take away". He told me they keep 2 hours without refrigeration, and till night in your fridge. He was right, I believe he cannot go wrong, period.
If you eat lunch, there are three smallish tables where to enjoy your meal. Even if it's a lunch place it is too small to allow for more sitting space.
I'm an eel fan but Rob offers also herring, salmon, mackerel, cod and others I was not able to identify. If you sit at a table you can also have a salad.
Since Rob is so good, there is now copetition on that block of Zoutsteeg. Don't be fooled, if you come from the Rokin, Rob is the SECOND "vis" sandwich shop.
I'm very far away from Amsterdam now, but as I write my mouth waters. Please, have one for me!
