Re: Registration Statement on Form S-8

Ladies and Gentlemen:

We have acted as counsel to Potbelly Corporation, a Delaware corporation (the “Company”), in connection with the registration statement on Form S-8 (the “Registration Statement”) relating to the registration under the Securities Act of 1933, as amended (the “Securities Act”) of 900,000 shares of the Company’s common stock, par value $0.01 per share (the “Shares”), issuable pursuant to the Company’s 2019 Long-Term Incentive Plan, as amended and restated (the “Plan”).

As counsel to the Company, we have examined the Company’s amended and restated certificate of incorporation, amended and restated bylaws and resolutions of the board of directors and stockholders of the Company. We have also examined such other documents and instruments and have made such further investigations as we have deemed necessary or appropriate in connection with this opinion. In expressing the opinion set forth below, we have assumed the genuineness of all signatures, the conformity to the originals of all documents reviewed by us as copies, the authenticity and completeness of all original documents reviewed by us in original or copy form and the legal competence of each individual executing any document. As to matters of fact (but not as to legal conclusions), to the extent we deemed proper, we have relied on certificates of responsible officers of the Company and of public officials.

Based upon and subject to the foregoing, and having regard for legal considerations which we deem relevant, we are of the opinion that the Shares have been duly authorized and, when issued and sold in accordance with the Plan, will be validly issued, fully paid and non-assessable.

The opinion expressed above is limited to the Delaware General Corporation Law and we express no opinion with respect to any other laws.

We consent to your filing this opinion as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Securities and Exchange Commission thereunder.

Very truly yours,

/s/ Mayer Brown LLP
