Trzópek's first job in gastronomy was at his friends' fried fish shop in the seaside. He later polished his skills at restaurants, e.g. in Gdańsk in Długa Street, or at the Oliwa Manor (Dwór Oliwski). The chef at the latter hotel restaurant imported ingredients from France, thus making the young cook aware of the importance of the quality of produce.
In 2003, Trzópek went to Great Britain to further improve his skills. He wanted to work with the best, and he managed to achieve that. First, he was an apprentice in Guildford, near London. In his opinion, his true breakthrough came while he was working at Le Manoir aux Quat' Saisons in Oxford. The restaurant, in which he he spent three years, holds two Michelin stars, and has had such famous employees as Gordon Ramsay and Heston Blumental. At Le Manoir aux Quat' Saisons, Trzópek was responsible for amuse-bouche, hot and cold starters, fish, garnishes, sauces, vegetables, meats, and patisserie. He recalls that, while working abroad, he was most astonished by the regular use of highest quality products. In Trzópek's opinion, it is the ingredients that determines a dish's flavour.
