Had raclette one night, all you could eat, for ~5 Swiss francs. Obscenely great exchange rate at the time, so it came out to about $1.50.
Your picture shows the fancier, modern version, with updated veggies.
IIRC, raclette was originally a shepherd's meal of fire-melted and scraped cheese, baby potatoes, gherkins, pickled onions, and I think some trockenfleisch.
